Help find the measure of b
b= 81 degrees
Explanation:
A straight line is 180 degrees.
180 - 99 = 81
All the angles combined should be equal to 360, forming a circle.
In order to find angle b, we have to know what supplementary angles.
Supplementary angles are two angles that add up to 180°, or in other words, a straight line.
Angle b and the 99 degree angle are supplementary due to them creating a straight line when combined, so they add up to 180°.
To find angle b, subtract 99 degrees from 180.
180 - 99 = 81
Angle b is equal to 81 degrees.

What’s is your average speed in miles per hour and in feet per second if you travel a mile in 26 minutes?
To calculate the average speed, divide the total distance travelled by the total time taken. The speed is approximately 2.31 mph and 3.385 fps.
Explanation:To calculate the average speed you divide the total distance travelled by the total time taken. In this case, the distance is one mile and the time is 26 minutes.
To get the speed in miles per hour (mph), first convert the time from minutes to hours by dividing the time in minutes by 60. So, 26 minutes is approximately 0.43 hours. Then, divide the distance by the time to get the speed. Therefore, your speed is roughly 2.31 mph.To convert this to feet per second (fps), first convert 1 mile, which is 5280 feet. Then convert the time from 26 minutes to seconds, which is 1560 seconds.So, when you divide distance by time, you get approximately 3.385 fps.

The figure below is a square pyramid where the height of the pyramid is 2 centimeters and the volume is 24 cubic centimeters. If the volume of a pyramid is v=1/3bh, then what is the length of the base?
A.2cm
B.4cm
C.6cm
D.8cm
Final answer:
The length of the base of the square pyramid is calculated by rearranging the volume formula v = 1/3bh to solve for b, finding the base area, and then taking the square root to find the side length. With the given volume of 24 cm³ and height of 2 cm, the side length of the base is 6 cm. Therefore, the correct answer is C.
Explanation:
The student is asking how to find the length of the base of a square pyramid given its volume and height. The volume of a pyramid is given by the formula v = 1/3bh, where v is the volume, b is the area of the base, and h is the height. Since the pyramid is square, the area of the base (b) is equal to one side of the square base squared. With a volume (v) of 24 cm³ and a height (h) of 2 cm, we can substitute the values into the formula and solve for the base area b.
To find the side length of the base, we take the square root of the base area. Using the provided formula and values, we get:
v = 24 cm³
h = 2 cm
b = (3×v)/h = (3×24 cm³)/2 cm = 36 cm²
The side length of the base (l) is the square root of the base area: l = √b = √36 cm² = 6 cm. Therefore, the correct answer is C. 6 cm.

Explain how comparing 645 and 738 is different from comparing 645 and 649
When comparing these two sets of number, the first set is harder to find the different as you need to borrow from a column. For instance, when you start subtracting in the 10s place, you cannot take 40 away from 30.
Whereas in the second set, comparing the numbers is easy. They have the same 100s value and the same 10s value. You are simply comparing the 1s place.
Answer:
First, if we compare 645 and 738, the difference is significant, because those number have different units, different tenths and different hundreds.
However, if we compara 645 and 649, the difference isn't significant, because they have the same hundreds, the same tenths, but different units.
So, in terms of comparing numbers as such, we can tell that the difference in each comparison is about units, tenth and hundreds difference.
From this different comparison, the difference operation (subtraction) is also different, because it's not the same to subtract 645 from 738 than from 649, the difference is higher.

simply each expression, use the distributive property to clear parentheses then combine like terms
6(x-2)+5x
Answer:
11x - 12
Step-by-step explanation:
Distributive property, also called the distributive law of multiplication and division, lets us distribute a number by multiplying it to each of the numbers in a term separately.
We can expand this expression by clearing the parentheses and combining the like terms here by applying the distributive property:
6 (x-2) + 5x
6x - 12 + 5x ---> (6 is multiplied to both the terms, x and -2, separately)
Now we will combine like terms to get:
6x + 5x - 12
11x - 12

Violin strings are parallel. Viewed from above, a violin bow in two different positions forms two transversals to the violin strings. Find x and y in the diagram.
ANSWER
[tex]x=10[/tex]
and
[tex]y=20[/tex]
EXPLANATION
Since corresponding angles are equal,
[tex]4x+y=60---(1)[/tex]
Alternate angles are also equal, therefore,
[tex]8x+y=100---(2)[/tex]
Equation (2) minus equation (1) gives,
[tex]\Rightarrow 4x=40[/tex]
[tex]\Rightarrow x=10[/tex]
We put [tex]x=10[/tex] in to equation (1)
[tex]4(10)+y=60[/tex]
[tex]y=60-40[/tex]
[tex]y=20[/tex]
To find x and y in the violin string diagram, use the properties of angles formed by transversals and parallel lines. Corresponding angles and interior angles are key relationships. In the example, x = 15° and y = 90°.
The problem involves understanding the relationships between angles formed by transversals and parallel lines. When a violin bow is placed across parallel violin strings, it forms transversals that create various angles.
Given that the violin strings are parallel, the interior angles formed on the same side of the transversal are supplementary. Let's consider the setup of the diagram:
Identify corresponding angles, alternate interior angles, and alternate exterior angles.Use the properties of parallel lines and transversals to set up equations.Solve for the unknowns (x and y).Example: Suppose the violin strings and the bow are positioned in such a way that we can see the angles formed. Assume the given angles are as follows:
Angle 1 = 30° (corresponding angle)Angle 2 = (2x)° (alternate interior angle)Angle 3 = y°Step 1: Since Angle 1 and Angle 2 are corresponding angles and lie between parallel lines:
30° = 2x → 2x = 30° → x = 15°
Step 2: To find y, use the fact that the sum of angles around a point is 360°. Suppose y is opposite to the sum of Angle 1 and another given angle on the same side:
If the other angle on the same side is 60°:
y = 180° - (Angle 1 + 60°) → y = 180° - (30° + 60°) → y = 90°
Thus, the values of x and y are determined to be 15° and 90°, respectively.

How can you tell if a mixture is homogenous or heterogeneous?
A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions. A heterogeneous mixture consists of visibly different substances or phases. The three phases or states of matter are gas, liquid, and solid.
Final answer:
A mixture is heterogeneous if it has a non-uniform composition, wherein the individual components can often be seen or separated. A mixture is homogeneous if it is uniform throughout, where the components are evenly distributed and cannot be visually distinguished. Examining the uniformity of the mixture's composition allows for differentiation between the two types.
Explanation:
To tell if a mixture is homogeneous or heterogeneous, one must first understand the definitions of these terms. A heterogeneous mixture has a composition that is not uniform throughout. Examples include trail mix, salad, and blood. These mixtures often allow the individual substances within them to be seen or separated by simple means, such as filtration or inspection.
In contrast, a homogeneous mixture is uniform in composition throughout the sample. Examples include air, simple syrup, and seawater. For instance, when salt is dissolved in water to create a saline solution, it is a homogeneous mixture because the salt is evenly distributed throughout the water and no longer visible as a separate substance.
Distinguishing between these two types of mixtures involves examining the uniformity of the mixture's composition. If different samples of the mixture have different compositions, or if the individual parts can be seen, it is heterogeneous. If it is uniform and the components cannot be visually separated, then it is homogeneous.
what is the coordinate of the midpoint of line segment Q(-3,14) and R(7,5)
We can find the midpoint by using the two given coordinates and finding the average between them.
We will find the average between the x coordinates and the y coordinates.
We are given these two coordinates of line segment QR: (-3, 14) and (7, 5). Find the midpoint by finding the average (or mean) between the x coordinates (-3 and 7), and the y coordinates (14 and 5).
Find the average by adding up the two coordinates then dividing the answer you get by 2 (because you added two numbers).
x coordinates average: -3 + 7 = 4, 4/2 = 2; their average is 2
y coordinates average: 14 + 5 = 19, 19/2 = 9.5; their average is 9.5 (or 19/2)
Take the two averages and put them together so your answer is: the coordinate of the midpoint of line segment QR is (2, 19/2).
Two sides of an obtuse triangle measure 10 inches and 15 inches. The length of longest side is unknown. What is the smallest possible whole number length of the unknown side?
Answer:
24 inches.
Step-by-step explanation:
Two sides of an obtuse triangle measure 10 inches and 15 inches.
The length of the longest side is unknown.
We have to find the smallest possible whole number for length of the unknown side.
Since a triangle is possible only when sum of two sides of the triangle is greater than the third side.
Therefore, length of third side < sum of other two sides
length of third side < 10 + 15
length of third side < 25
Therefore smallest whole number length should be 24 inches.
